ABB PM862K02 Redundant Processor Unit

TRG-A/B connected to GND (normally-open switches). The active level (default is active low) can be changed with the INLVL command. These inputs are like the general-purpose inputs on the 50-pin header. The differences are (1) the triggers are pulled up via the AUX-P pull-up terminal and powered by the voltage applied to the V_I/O terminal; and (2) the triggers can be programmed with the INFNCi-H command to function as position capture inputs and registration inputs.

+5V connected to AUX-P and V_I/O 

 Provides +5V power to the TRG-A & TRG-B input pull-up resistors. As an alternative, you can connect AUX-P to an external supply of up to +24V (but do not use both the on-board +5V terminal and an external 5-24V supply). If V_I/O is connected to a +5V supply (on-board or external), AUX-P can be connected to a supply of up to +24V. If V_I/O is connected to an external +24V supply, AUX-P must also be connected to +24V (or to GND). Switching levels depend on voltage at V_I/O (LOW £ 1/3 of V_I/O volts; HIGH ³ 2/3 of V_I/O volts). NOTE: AUX-P and V_I/O are also used by the HOM, NEG, POS & P-CUT inputs. SINKING CURRENT: To make the trigger inputs (as well as HOM, NEG, POS & P-CUT) sink current, connect AUX-P to GND.
